Starting from this state, the cover 200 is further rotated, and then the inclined surface 204 will further push the peripheral edge elastic sealing protrusion 丨 〇5, thereby urging the aforementioned peripheral edge sealing wall 2 05 to press the elastic protrusion 1 〇5 At the top, at the same time, the aforementioned male sealing protrusion 106 is also inserted into the fitting groove 206 to form a tightly closed state (see FIG. 3). ° Haifeng i 2 0 0 must also be connected to the water outlet part i 〇 3 of the water outlet part i 〇 〇 by using a single-touch (0 n e _ 10 u c h) bonding method instead of the screw connection method. Figures 4 to 11 show various modified examples of the male seal structure in the present invention.

200418712 V. Description of Invention (5) First, please refer to Figures 4 and 5. In the figure, the elastic protrusion 105 is formed at the top end of the aforementioned water outlet portion 103 and is bent forward or backward. In practical application, the elastic protrusion 105 is elastically embedded in the cover 200-fitting groove. Second, see Figures 6 and 7. The elastic protrusion 105 in the figure is formed by extending upward from the inner wall of the aforementioned water outlet portion 103. In practical application, the elastic protrusion 105 is tightly closed by being elastically squeezed by the inner wall or the outer wall of the inner cover 203.

Next, please refer to Figures 8 and 9. In the figure, the male sealing protrusion 106 is defined as a peripheral step formed on the top of the water outlet portion 103. In practical application, the fitting groove 206 of the aforementioned cover 200 is matched with the peripheral stepped male sealing protrusion 106 to form a tightly closed state. Secondly, please refer to Figures 10 and 丨 丨. The design of the stepped male seal protrusion 106 in the figure is a posture that can be bent outward. In actual application, the top of the peripheral stepped male sealing protrusion 106 provides a tightly closed structure after the fitting groove of the cover 200 is bent '. Fig. 12 shows a modified example of the female sealing structure in the present invention.

As shown in the figure, the aforementioned water outlet piece 100 includes a peripheral edge elastic sealing protrusion inclined at a predetermined angle from its inner wall 104 as a male sealing structure, and formed at the top of the water outlet portion 103. The male seal bulge 丨 〇6. The cover 200 corresponding to the water outlet piece 100 includes an inner cover 203 having a slanted wall 204 at the bottom end. A secondary coupling groove 208 is formed on the top and bottom surface of the cover 200 and located on the inclined wall 2042, for the peripheral elastic protrusion 1q5 to be embedded. In addition, a top-bottom surface of the cover 200 is further provided with a _fitting slot 206 for the male back-seal protrusion 106 to fit.

Figure 13 is a detailed view of the water outlet piece. As shown in the figure, a disposable locking ring fixing portion 108 and a hook protrusion forming portion 109 are provided between the water outlet portion 103 and the coupling portion 101, and the coupling portion 101 and A first space Ul and a second space are defined between the hook protrusion forming portions 109. The combining portion 101 extends downward to form guides 丨 丨 3, 丨 丨 4 to guide the combining portion 101 into the container body 300.

The coupling section 101 is coupled to the container body 300 by a hot pressing method. During the process, the container and the joint portion will partially melt. At this time, the molten material will flow into the second space 1 1 2 to prevent the appearance of the container from being damaged. Fig. 14 shows the structure of the hook process forming portion.

As shown in the figure, the hook protrusion forming portion 109 is provided with a plurality of hook protrusions 110. The cover 2 0 has a locking ring 2 11 provided with a plurality of elastic protrusions 2 1 0. The plurality of elastic protrusions 2 10 are the connecting portions 209 of the locking ring 211 provided by the hook protrusions used to disassemble the cover 200. When the cover 200 is combined with the aforementioned water outlet piece 100, the hook protrusions 丨 丨 and the elastic protrusions 2 10 are designed with different distances A, B, C, and D, respectively. When the cover 2 is opened, the connecting portion having the shortest distance A is broken first, and the connecting portion having the longest distance D is finally broken. The sizes of these distances A, B, C, and D can be reduced or randomly arranged during design. In addition, a cutting line must be provided between the locking ring 211 and the cover 200 to replace the connecting portion 209. In this way, when the elastic protrusions 210 are hooked on the hook protrusions 110, the locking ring 2 11 is peeled off. FIG. 15 shows a modification of the hook formation portion 109 and the locking ring 2 1 1

Page 10 200418712 V. Description of Invention (7) Example. As shown in the figure, the water outlet piece 100 is provided below the water outlet portion 103 with a plurality of hook protrusions Π and elastic hook protrusions 115 for the locking ring 2 11 to be hooked. The locking ring 2 11 has a plurality of elastic protrusions 210 that can be hooked on the hook protrusions 110 or the elastic fishing protrusions 115. In addition, the locking ring 211 further includes a plurality of connecting portions 209 located near the elastic protrusions 210, and a plurality of blocking protrusions located near the connecting portions 209. ° Caps 200 and 16 are shown in Figures 16 and 17. The locking ring 2ΐ of the cover 200 is coupled to the bottom of the side portion 202 through the connecting portion 209, and the elastic protrusions 210 are formed on the inner wall of the locking ring 21ι and are inclined at a specific square. A water outlet structure with a straw is shown in Fig. 18 to 0 and Fig. 18. As shown in the figure, a suction tube 400 penetrates the water from the water outlet member to form a tightly closed state with each other. When using the day guard, just squeeze the container and the contents can be discharged through the side hole 401 for users to suck. Industrial Applicability <
